Current Question (ID: 19100)

Question:

$\text{A ball is thrown horizontally from height of 10 m with a speed of 5 m/s as shown.}$ $\text{What would be the speed with which it strikes the ground?}$ $\text{(Take } g = 10 \text{ m/s}^2)$

Options:

1. $15 \text{ m/s}$
2. $5 \text{ m/s}$
3. $10 \text{ m/s}$
4. $20 \text{ m/s}$

Solution:

$v^2 = u^2 + 2gh$ $v^2 = 25 + 2 \times 10 \times 10$ $v = 15 \text{ m/s}$
